Installation; Preparation Before Start-Up; Transfer Switch; Fuel System - Generac Power Systems 4.6L Owner's Manual

INSTALLATION

Refer to the separate "Installation Guide" supplied with the unit.
For safety reasons, the manufacturer recommends that this equip-
ment be installed, serviced and repaired by a Service Dealer or
other competent, qualified electrician or installation technician who
is familiar with applicable codes, standards and regulations. The
operator also must comply with all such codes, standards and
regulations.

PREPARATION BEFORE START-UP

The instructions in this section assume that the Stationary
Emergency Generator has been properly installed, serviced, tested,
adjusted and otherwise prepared for use by a competent, qualified
installation contractor. Be sure to read the "Safety Rules", as well
as all other safety information in this manual, before attempting to
operate this (and related) equipment.
Before starting the generator for the first time, the installer
must complete the following procedures. For follow-up mainte-
nance information and/or service intervals, please refer to the
"Maintenance" section and the "Service Schedule".

TRANSFER SWITCH

If this generator is used to supply power to any electrical system
normally powered by an electric utility, the National Electrical Code
requires that a transfer switch be installed. The transfer switch pre-
vents electrical backfeed between two different electrical systems.
(For additional information, see the applicable transfer switch
manual for this unit.) The transfer switch, as well as the generator
and other electrical components, must be properly located and
mounted in strict compliance with applicable codes, standards
and regulations.

FUEL SYSTEM

Make sure the fuel supply system to the generator (a) delivers the
correct fuel at the correct pressure and (b) is properly purged and
leak tested according to code. No fuel leakage is permitted. See
"Specifications" for more information.

GENERATOR SET LUBRICATION

Check the engine crankcase oil level before operating and add
oil to the proper level – the dipstick "FULL" mark. Never operate
the engine with the oil level below the dipstick "ADD" mark. See
"Specifications" and "Engine Oil Recommendations".
Check the oil level in the generator gearbox (if so equipped) prior to
initial use and at the intervals indicated by the "Service Schedule."
The recommended oil is SAE 90 gear lubricant.
This engine is shipped from the manufacturer with "break-in"
oil. This oil should be changed after 30 hours of operation.
NOTE:
Installation

PRIOR TO INITIAL START-UP

Prior to initially starting the generator, it must
be properly prepared for use. Any attempt to
crank or start the engine before it has been
properly serviced with the recommended types
and quantities of engine fluids (oil, coolant,
fuel, etc.) may result in an engine failure.
ENGINE COOLANT
Have the engine cooling system properly filled with the recom-
mended coolant mixture. Check the system for leaks and other
problems. See "Specifications" and "Coolant" sections.
BELT TENSION
Check-the engine-fan belt tension and condition prior to placing
the unit into service and at recommended intervals. Belt tension is
correct when a force of approximately 22 pounds (10 kg), applied
midway between pulleys, deflects the belt about 3/8- to 5/8-inch
(10 to 16 mm).
ELECTRICAL SYSTEM
Make sure the generator is properly connected to an approved
earth ground.
Make sure the generator battery is fully charged, properly installed
and interconnected, and ready for use.
Battery charger must be connected to 120 VAC, 15 amp circuit
to operate.
Check to ensure that there are no loose electrical connections.
Restrain any loose wires to keep them clear of any moving genera-
tor set components.
INITIAL INSPECTION FOR GENSET
STARTUP
Inspect for the following.
• Freight Damage.
• Manuals present.
• Fluid Levels (Oil, coolant, battery, Gear Drive).
• Correct fuel piping.
• Correct muffler installation for external applications (open units
only).
• Adequate air flow, clearances and ventilation per installation
drawings and applicable codes.
• Correct AC and DC wire size, connections and grounding.
Control and communication wiring to/from the transfer switch
must be run in a separate conduit from the AC power leads.
• Battery charger connection to 120 VAC.
• Unit secured to pad.
